Copper

Copper ( / ˈ k ɒ p ər / kop-ər) is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. The metal and its alloys have been used for thousands of years. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as сyprium (metal of Cyprus), later shortened to сuprum. Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris (or patina). Decorative art prominently features copper, both by itself and as part of pigments. Copper(II) ions are water-soluble, where they function at low concentration as bacteriostatic substances, fungicides, and wood preservatives. In sufficient amounts, they are poisonous to higher organisms; at lower concentrations it is an essential trace nutrient to all higher plant and animal life. The main areas where copper is found in animals are tissues, liver, muscle and bone. From Wikipedia under the

I'm working with little copper plaques of 2.5 cm x 2.5 cm x 0.6 mm. I have to connect them with other things so i need to use skinny copper wire, The thing is that I don't know in what orders of magnitude they exist in commerce. Any idea of which would be reasonable? Thanks ! Asked by - Sat May 21 18:53:28 2011 - Other - Science - 1 Answers - Comments A. If you have some old electrical appliances that don't work, take them apart before you throw them away. Depending on what it is, it might have a lot of copper wire in it, wire of different sizes. Otherwise, you can go to a hardware store and check out what selection they have. Copper is produced in many different sizes of round stock, from as small as your hair to bigger than your thumb.

Thanks :D Asked by College Student - Mon Jul 7 18:08:38 2008 - Chemistry - 1 Answers - Comments A. Copper has two common oxidization states. Copper ions are commonly found as either Cu+1 or Cu+2 ions. Thus, you can find two different types of Copper Sulfide. There will be Copper(I) Sulfide, Cu2S, and also Copper(II) Sulfide, Cu S. We can differentiate between the two if we include the charge on the Copper ion in the chemical name (in Roman numerals) as I did, or we can use the older nomenclature to distinguish which Copper ion we are dealing with. In the older nomenclature, Copper(I) ___ was called Cuprous ___ , and Copper(II) ___ was called Cupric ___ . Therefore, we could have Cuprous Sulfide or Cupric Sulfide. Do you know which you are dealing with? Copper(II) salts are more common, so if you don t know then assuming Cu S would not… [cont.] Answered by mrjeffy321 - Mon Jul 7 18:35:00 2008 From Yahoo Answer Search: "copper" |
